Sculpin expansion origin issues...trial 2 days in

LightBurn Hardware Compatibility Sculpfun
8

Not sure of the difference between S6 and S9 and the Sculpun website seems to be oddly silent on it.

Typically for machines without end stops you will need to manually position the head of the laser to the front left of the machine before turning on the controller. The position you start from is set to 0,0. From that point software limits should prevent most crashes into the frame.

There can be complications that prevent this from working in some cases so let’s walk through any of those.

Confirm that starting position is indeed 0,0 by moving head to front left and cycling power on the laser. Then check Get Position in Move Window.

If the coordinates are indeed 0,0 then you’re good to go and you’ll be able to use Absolute Coords as well as the other 2 coordinate systems. I’d recommend sticking with Absolute Coords until you have a good feel for how the laser and LightBurn work.

If it’s not 0,0 then run the following commands in the Console window and copy back all the output here:

$I
$$
$#
?

Also, I haven’t seen any direct messages from you so not sure what’s going on there.

hi, thanks for that.

I will continue with instructions but im not sure what you mean by ‘copy back the output’ ?

Screenshots of each command result?

thanks

Hi, I seem to be getting some were!

kinda sorted an artificial home position using the go’ function and navigated the laser around and no banging into the rails at all!
Whoooh!

No actual layering yet…

I will keep in touch for further progress.

what a relief.

special thanks to Berainlb for your help , during holidays too!

Just to confirm, what is your position after starting the machine from the front left?

12

Hi, when i start machine with laser theres no movement to any piont or any sounds or single its on.

When lightburn is opened theres a little noise that sounds like the machine/gears are talk ing to each other ready to engage but no movment.

I have to move the laser head manually by hand or jog to the left front. Then ‘get positioned’ to make it 0.0

I also jog it 5mm OR 10mm X and Y away from the rails, this becomes the 'home position kind of :slight_smile: .

The software reads at 0.0 etc regardless of were the laser module is on the machine when both are turn on.

hope this helps

Thnks

Okay. So this is working as expected. Wherever the head happens to be at start-up is 0,0.

You should not need to “pull-off” away from the rails if you’re following the process of starting up in the front-left. You can power cycle the laser if you needed to manually move the laser head there to get to 0,0. You can alternatively issue a “G92 X0 Y0” in console (without quotation marks) if you want to zero-out without power cycling.

14

This were I go a bit blank. As I have never used one before and have never seen the console codes ever before or even new they existed. When I am asked to do such a thing I am blank as to what to actually physically do to…i.e. “change gear” in an automtic car verse a manual, some people have never seen a manual so changing gear would require a bit extra trial…so bare with me hahaha.

I tried to type in G92 X0 Y0 in the console bar at the botttomof window but nothing happened…asumming this is correct place to type it.

15

You would enter the commands into the area of Console where it says “(type commands here)”. The command isn’t “registered” until you press enter. After that, you’ll probably see something show in the small screen above to acknowledge the command.

If you enable the slider “Show all” you’ll see all the chatter between LightBurn and the laser controller.

You should at least get some acknowledgement in the console output window but can’t recall exactly what. How you can tell for sure if it worked is if Get Position in Move window shows 0,0 after being pressed. This should be true no matter where the laser head is positioned when you run the G92 command.

Alternatively, you can get the position information in Console by entering ? followed by enter.

16

how do I insert an image to a post? all screenshots I have had to email as they won’t upload in the posts…I waited 5 mins for image to upload but still hasn’t. email takes 2 seconds…
and I can’t exit upload other than canceling the whole post a re typing.

anyway…
I typed G92 X0 Y0_enter but 'get positioned is not 0.0

17

As a ‘new’ user you are limited on how many things you can post…

:smiley_cat:

18

ok, thanks.

19

hopefully I’m not breaking the new user rules already …this will be my last post.

Is there any sculpfun users that can help me with running the machine in light burn?

are there nuances in that difer from other machines.

thank you to everyone who helped.

Another user of Sculpin is having some issues. I reference them here, but I thought I might let you try ‘over there’… :crazy_face:

:smiley_cat:

21

What was the value?

22

Warren2, I have come up with very similar problem on my Sculpfun S-9 as you seemed to have worked on. Machine is only a week old so still not sure it’s not defective. It did work initially but now it will not set on home point 00 after attempts and also locks with gurbl alarms after it hits the rails. It also will no longer jog from the move window. Pretty much a disappointment so far. Any help appreciated.

Hi, sorry late reply…I had some time out from the laser to recover in the woods lolol…once i had finally got the navigation sorted…

Your situation sounds very odd indeed. For the move tool not to function suggests motherboard issue etc.

My issue was i assumed like a dumdass that the circuitry had Homming etc in it like almost all other lasers.

Once i finally figured that out it was really just mannually positionng the laser in the bottom left before turning on the laser and me just using one of the origin settings(absolute)…in light burn, it started to make sense.

I had NOOO experiance with lightburn at this piont aswell ,so that didnt help, although it is very 'logical to use…just time in the interface was needed from that piont.

1, What i did was: BEFORE TURNING ON MACHINE… Move the laser as far as possible to the bottom left of the laser up to the rails…you could give a 1-2mm gap if comfortable that.

 this is just to have it in a artificial origin of what a homing setting would be....THEN OPEN LIGHTBURN . It should read 0.0 on the lightburn interface.

  1. Ignore the home button in the interface ( MINE DOSENT WORK either), focus on the jogging arrows.
    try to jog the laser up and to the right away from the left 0.0 corner…then back again…say 5mm increments.

  2. now try to set a position in the “MOVE TO POSITION” say 20mm X and 20mm Y ,then hit the "GO " button.
    it should move to that position from your 0.0…theeeennnn…

  3. Then enter 00.00 in X and Y in the move to postion’ area and hit Go’… Hopfully it should return to the 0.0 were it was positioned when you first turned on the machine.
    If it worked, turn off machine and see if you can repeat the exercise.

This is the only way i can predict were the laser will move to.

If you put the laser in the middle of the machine and turn on machine that will be 00.00.
Or if you move totally to the right bottom of machine and turn it on, that will be 00.00
if you put it at the very back and turned on the machine , that would be 0.0

Remember that from each side 0.0 of the machine you can only position/type 410mm or less from 0.0 across/side to side…there are no limit swithches so it will hit rails if it is more than a 410mm position…
Apprently there are ports for the limit switches on the board.(out of my expertise but will look into it).

This is what i have done to atleast get started, i still stuff it up sometimes, …so annoying but it s the only way so far i know.

Yours does sound like a machine fualt though, total bummer if so.

Let me know how you go.

Im back at work and will keep eye on email.

Chur and good luck.

Thank you, yep had 4 days of fun now trying to get the machine back on track. With no help from Sculfun we have narrowed it down to a chip issue and have been trying to get a correct flash that will work for the firmware. All of what you have indicated I have now been through too many times to remember (almost seeing in my sleep now). Thank you for your help will let you know if it ever gets solved.

25

You are fine, and I bumped your status. Should be able to upload more now. :slight_smile:

26

HI, so I managed to get some test cutting done like a bout 5 OF THEM on paper and card to get use to navigating laser as of a week-10 days ago.

First day back on the machine since then and it won’t be seen by the software or its just not sending a signal(broken already) lolol and won’t jog etc etc etc… Processing: Screen Shot 2022-01-12 at 9.12.10 PM.png…
Uploading: Screen Shot 2022-01-12 at 9.12.45 PM.png…
can some check my settings screen shots, maybe I missed something.
Assuming I can upload them as I could through out the whole last thread.

I just uploaded them to a email as this is taking way too long as per last time…

Thanks
